PHPP 101: Fundamentals of the Passive House Planning Package

October 4 @ 9:00 am - 12:00 pm


Join us for this training on the software at the core of the Passive House movement. Add tickets to the cart on the bottom of this page to register.

With each iteration of the PHPP (Passive House Planning Package), Passive House practitioners get more powerful tools to reduce building energy by design. Of particular importance to the US audience, the version of PHPP 9 in Imperial Units (PHPP 9 IP) has been released, which is the first energy modeling software for the non-metric world to combine low-energy design with renewable energy supply to create cost effective solutions.

Beginners / Those In Need of Refresher

Learning Objectives:

  1. Learn the history of the PHPP and why it is the basic building block for the Passive House movement
  2. Understand what PHPP is capable of providing as a design tool
  3. Introduction to the inputs and outputs, and how to enter a model
  4. Get the skills you need to start your projects on the Passive House path

How to Prepare for the Event

Participants need only have a laptop with a registered version of PHPP (version 9 preferred). If you do not have PHPP, you can purchase it from 475 here.

PHPP_screenshotIf you’re the type that enjoys numbers, you’ve done this: started a major project by opening up a blank Excel sheet and playing with some numbers to get a sense for your limits. Then you go from there, adding complexity and detail until you get the refinement you need and feel comfortable with and answer that reflects reality.

We say “software” when referring to PHPP, but as you may know, it’s an Excel spreadsheet. Since its development in 1998, it has been continuously tested and re-created to account for conditions around the globe, in every climate. The first editions looked primarily at space heating balances and for heat distribution and supply, as well as for the electricity and primary energy demand. As versions advanced we saw the addition and deepening integration of windows, shading, heating load and summer behavior, cooling and dehumidification demand, ventilation for large objects and non-residential buildings, taking into account of renewable energy sources, and retrofitting of existing buildings. The PHPP is continually being validated and extended on the basis of measured values and new research findings.

Ongoing PHI scientific research measures results and compares them with the calculated results. The result is a high correlation demonstrated between the PHPP demand calculations and the scientific monitoring of projects. With careful planning of building efficiency, there will be no performance gaps.
